摘　　要：对浙江、湖北、江苏等省3个野生茭白材料17个不同品种的茭白种质资源进行了收集,利用ISSR方法对茭白植株进行了基因组多态性分析.结果表明,野生茭白与栽培茭白品种间具有明显的多态性,不同来源的栽培茭白品种间也具有一定的多态性,多态性比例分布在12%-25%之间.利用DPS软件对茭白植株的多态性位点进行的系统聚类分析发现,野生茭白与栽培茭白间距离较远,茭白地域分布及栽培特性与种质资源多样性相关。Twenty different varieties of Z. latifolia germplasm resources were collected; and genomic polymorphism analysis based on the ISSR method was carried out. The result showed that there was a significant polymorphism between the wild and the cultivated varieties, while different sources of the cultivated also exhibited genomic polymorphisms with a distribution of 12%- 25%. A preliminary cluster analysis for the polymorphism locus of Z. latifolia using DNS shows that there is obvious distance in Z. latifolia between the wild and the cultivated varieties. The distribution and cultivation characteristics of Z. latifolia are related to the genetic diversity.
